Title: Front fender structure for protecting a walker
Inventor: LEE DONG YEOL
IPC: B62D25/08
Filed: 2000-12-18
Abstract: PURPOSE: A structure of a front fender for protecting a pedestrian is provided to buffer impact to a pedestrian's head as absorbing impact from collision when the pedestrian's head is bumped into a vehicle. CONSTITUTION: A front fender(1) is installed in a wheel apron damper(3) through an impact-absorbing member(2). The impact-absorbing member has a deforming part(4) projected to the inner side and being deformed by impact in the center, and is installed in the wheel apron damper vertically by many coupling tools. The impact-absorbing member has many screw holes(5) like a welding nut on the deforming part. The fender is connected to the impact-absorbing member and the coupling tool is coupled in the screw hole from the fender. The fender has long holes(8) penetrated by the coupling tools coupled in the screw hole of the impact-absorbing member, and is installed in the impact-absorbing member by the coupling tools as being located the lower part of the long hole in the screw hole. If the impact is applied in the upper part of the front fender, the deforming part is deformed to be protruded more and absorbs the impact. The front fender is pushed to the lower part by the impact because the front fender is installed in the impact-absorbing member by the coupling tool penetrating the lower part of the long hole. The long holes guides push of the front fender when the front fender is pushed to the lower part of the impact. Because the long holes is formed toward the direction received the impact, resisting power about the impact is reduced. The impact is buffered in the deforming part and the resisting power of impact is buffered. The impact-absorbing member has a flange to prevent the front fender from being pushed to the lower part. The front fender is not pushed to the lower part by the flange.
